Fuel for Your Mower: What’s Best For You?

Sunday, April 5th, 2015

When it comes to the purchase of a new mower, you have more choices than ever before. Instead of merely the choice between a push mower and a riding lawn mower, today we have walk-behind mowers, stand-on mowers and zero-turn mowers to choose from.

Once you’ve decided which mower type you want, it makes sense to consider which fuel is your best option. Gasoline isn’t the only choice anymore. There are also a wide variety of propane lawn mowers to choose from. But which one is better, gasoline or propane?

Advantages of Propane

There are several advantages to propane as a mower fuel. For example, propane stores longer than gasoline. You don’t have to worry about fuel quality degradation over the winter, so you can store the mower in the garage and from a fuel standpoint, it’ll be ready to go when it’s time to mow again in the spring.

Propane is typically less expensive than gasoline. You’ll also find that propane prices don’t fluctuate as much as the price of gasoline. Since propane prices are often lower in the summer, propane-powered lawn mowers are becoming more popular with landscape professionals, too.

In addition to paying less per gallon, using propane also eliminates the possibility of a hazardous and costly spill. Propane also reduces the likelihood of fuel being stolen for use in other vehicles. Last but not least, propane is environmentally friendly. Propane-fueled mowers produce fewer greenhouse gasses than gasoline mowers, making them a good choice in areas where air quality is an issue.

When it comes to using propane-powered lawn mowers, it’s important to remember to fill the propane tank (or keep an alternate) before you start mowing. But propane’s growing popularity as an alternative fuel means you shouldn’t have trouble finding a filling station nearby.

Advantages of Gasoline

Gasoline-powered lawn mowers continue to be popular for a number of reasons, but universal fuel availability is a big one. If your mower runs out of gas, it’s easy to get it refilled. You can purchase gasoline at any gas station, virtually any time of day. Plus, it’s relatively easy to carry a small gas canister to and from the filling station.

Gasoline engines are available in a wide variety of sizes and configurations, so chances are you’ll be able to find a mower type and size to suit your needs. As a result, today, gasoline engines power the majority of our mowers.

Gasoline can for lawn mowerWhen Gasoline-Powered Mowers Make Sense

We recommend gasoline-powered lawn mowers to most homeowners. For a small or medium-sized property, you’ll find a wider variety of gasoline-fueled mower options suited to the task. While you may still like to take one of our zero-turn lawn mowers for a ride, you might be better served with a smaller self-propelled walk-behind for your property. And nine times out of ten, those mowers will be gasoline-powered.

For a smaller property, you’re not going to be mowing the yard for several hours. This means you probably aren’t going to use enough fuel each year to be able to realize a significant cost benefit using propane. Of course, that doesn’t mean you can’t purchase a propane-powered mower to maintain a small- to medium-sized property. But the difference in fuel cost really pays off for commercial and professional users.

When You Should Choose Propane

Propane-powered lawn mowers, whether they are zero-turn mowers or not, are most useful for commercial and professional users and large properties. Propane mowers give these users the opportunity to reduce fuel expenditures by up to 25 percent, which is a big deal. If you’re running your lawn mower for eight hours a day or more, you’re probably spending a lot of money on fuel.

When it comes to mowing the lawn professionally, it’s also a good idea to consider the environment. After all, switching to a propane-powered lawn mower is really noticeable when you cut grass for a living. Fortunately, you don’t have to trade energy efficiency for power. Thanks to state-of-the-art Kohler EFI-propane powerplants, our propane mowers offer exceptional performance while being easier on the planet.

If you are a landscape contractor, you may also want to look into grants or rebate programs from the Propane Education and Research Council (PERC), or other agencies to help you defray the initial cost of the propane mower. That said, even without financial assistance, your business would benefit from the cost benefits a propane mower will deliver over time.

Benefits of RED Technology Explained

Tuesday, November 19th, 2013

Last week’s GIE+EXPO wrap-up featured an image of the oil barrels Exmark used to demonstrate the fuel savings the EFI and RED Technology-equipped Lazer Z X-Series zero turn rider can deliver. Thanks to increased fuel economy of up to 40 percent, a contractor can save about $1,900 each season on fuel costs alone, based on current prices.

These barrels represent how much fuel (and money) a landscape professional can save running a RED-equipped Lazer Z X-Series mower. How much can you save, you may ask? If you run 600 hours, you'll save on average 550 gallons of fuel and have about $1,900 in your pocket!

With such heady efficiency claims, you may be wondering how RED works. In a nutshell, Exmark’s exclusive RED Technology is an on-board intelligence platform that enables communication and response between key systems. RED optimizes mower productivity and durability by actively monitoring and controlling key mower components including the engine and clutch.

Inside this plug resides the brains of the RED system.

RED Technology is Exmark’s green industry-specific adaptation of the active engine monitoring and control that makes modern automobiles so efficient and reliable. RED leverages other on-board engine technologies such as EFI and an electronic governor to deliver both increased efficiency and responsiveness.

The reduced droop of the electronic governor is a key feature that allows Exmark to achieve increased efficiency and performance on RED-equipped mowers.

The reduced droop of the electronic governor is a key feature that allows Exmark to achieve increased efficiency and performance on RED-equipped mowers.

The electronic governor significantly reduces governor droop to offer more consistent blade tip speed and a superior quality of cut. The increased responsiveness of the electronic governor also allows RED to feature three defined performance modes – Low, Efficient and Max. Instead of adjusting a throttle, the operator simply chooses the appropriate level of performance for the task, with the option to significantly reduce fuel consumption without impacting responsiveness when running in Efficient mode.

A three-position rocker switch replaces the mechanical throttle on RED-equipped machines.

Thanks to the responsiveness of the electronic governor, RED-equipped engines achieve maximum efficiency in Efficient mode, while operating at lower engine RPM. In this setting, blade tip speed is optimized for maximum cut quality and the mower not only uses less fuel, it is quieter and emits fewer emissions, with reduced overall machine wear.

RED also enhances the safety and durability of the Exmark mowers on which it’s equipped. It accomplishes this by actively monitoring vital engine and clutch components to prevent equipment failure in the field. If a situation such as high oil temperature or low oil pressure is detected, RED places the machine in a safe transport mode (clutch disengaged, 2,500 RPM) to prevent permanent damage and allow the machine to be returned for service.

In this age of $3+/gallon gasoline, it’s easy to dream about saving 40 percent on fuel costs. Today that dream is reality for RED-equipped Lazer Z X-Series owners. If you’re interested in living the dream, head out to the Exmark website to learn more about Exmark’s exclusive RED Technology and the Lazer Z X-Series mowers it’s featured on.

Green Machines

Wednesday, May 19th, 2010

We’re not surprised in the least to see a good deal of our customers opting for environmentally-friendly, alternative fuel mowers. It’s been a steady ripple of change within the landscaping industry. And pros are doing it for a variety of reasons, from customer expectations, to evolved business practices, to overall gas savings and efficiency.

Exmark is supporting our customers’ efforts with green machines that burn cleaner, reduce emissions and use less gas. We’re also hoping to educate everyone on the benefits of propane mowers.

For instance, along with the positive impacts of fuel  and environmental conservation, propane mowers require less maintenance and a clean-burning engine will actually last up to twice as long as a traditional engine.  Although there’s a bit of sticker shock associated with these mowers, propane is nearly 30 percent cheaper than gasoline, so the cost savings really add up. Translation: going green can save some green.

But if investing in a new alternative fuel mower is not an option, you can still take steps to go green by filling your Exmark with biodiesel. You’ll see very little impact on the performance of your mower.

Though alternative fuels may not be as readily available as gas, propane and biodiesel are not hard to find. Simply search your local Yellow Pages for your nearest propane dealer and The National Biodiesel Board for a list of registered fuel suppliers who adhere to strict production standards.

For those who prefer a gas motor but still want to reduce their gas consumption, take a look at Kohler electronic fuel injection engine (EFI), which uses significantly less gas, burns cleaner and produces far fewer carbon emissions than a traditional engine.  Similar to alternative fuel engines, you’ll spend less on fuel and need less maintenance.

Thinking about going green? Check out some Exmark’s alternative fuel mowers and EFIs.

Don’t forget to leave a comment and share your thoughts on the green issue.
